NCT04695964

Brief Summary

In this prospective, non-randomized cohort study, real-time intraoperative visualization using near-infrared-fluorescence by indocyanine green injection (ICG-NIRF) is performed at three time points during ileal pouch reconstruction. Postoperatively, a detailed software-based assessment of each pouch recording is performed to determine the objective ICG-NIRF perfusion rate, which is then correlated with the 30 day postoperative clinical outcome including occurrence of anastomotic leak of the pouch.

Study Arms (1)

ICG-NIRF Imaging and objective perfusion rate

OTHER

ICG-NIRF imaging is used to visualise the blood supply and the bowel perfusion rate in the area of the pouch anastomoses. An additional ingress and egress analysis at specific regions of interest is performed. This is to get an objective method of visualisation of the blood inflow and outflow over time and thus bowel perfusion at the anastomotic site.

Diagnostic Test: ICG-NIRF Imaging plus ingress and egress analysis

Interventions

intraoperative NIRF Imaging using the fluorescence agent ICG (indocyanine-green) at regions of interest before (T1) + after pouch construction (T2) + after ileoanal anastomosis (T3) Additional ingress and egress analysis (inflow and outflow analysis) of specificities regions of interest at regions of interest before (T1) + after pouch construction (T2) + after ileoanal anastomosis (T3)
